What is the formula for 3 phase power?
Use the Ohm’s law formula: Power (watts) = Voltage (volts) x I current (amps).
Arrange the equation for three-phase power to solve the current (amps): Current (amps) = power (watts) ÷ voltage (volts) ÷ square root of 3 (1.732) ÷ power factor; I = P ÷ (V_1.

How do you convert 230v AC to 12v DC?
The following are the steps to convert 230V AC to 12V DC.Transformer: Connect 230V AC to a 230 to 30V step down transformer. … Rectify: Connect a bridge made up of four Diodes. … Filter: Connect a filter, which filters out ripples from the signal. … Regulate: Connect a LM317, and regulate the output to 12V.
What is the formula of power factor?
This therefore gives us: Power Factor = Real Power/Apparent Power, or p.f. = W/VA. Then the cosine of the resulting angle between the current and voltage is the power factor. Generally power factor is expressed as a percentage, for example 95%, but can also be expressed as a decimal value, for example 0.95.
How do you convert 230v AC to 5v DC?
4 Steps to Convert 230V AC to 5V DCStep Down the Voltage Level. The step-down converters are used for converting the high voltage into low voltage. … Convert AC to DC. … Smoothing the Ripples using Filter. … Regulating 12V DC into 5V DC using Voltage Regulator.
How do you convert AC to DC?
Step 1: Choose the Transformer. In this project we choose a 12VAC 20VA transformer with screws at the bottom. … Step 2: Build the Bridge Rectifier With One Capacitor in Parallel With It. In this step, we build an bridge rectifier which make up of four 1N4001 diodes. … Step 3: Add the Voltage Regulator to Give 5v DC Output.
How is DC power calculated?
Through Ohm’s law, you can calculate the voltage (V), current (I) and resistance (R) of a DC circuit. From that you can also calculate the power at any point in the circuit. Follow Ohm’s law: Voltage (V) = Current (I) times Resistance (R).
How do you calculate AC current power?
The average ac power is found by multiplying the rms values of current and voltage. Ohm’s law for the rms ac is found by dividing the rms voltage by the impedance. In an ac circuit, there is a phase angle between the source voltage and the current, which can be found by dividing the resistance by the impedance.
What happens if you connect DC to AC?
If we connect an AC supply to the DC devices and equipment: The positive and negative voltage will destroy (this is not always the case) some of electronic components such as transistors and electrolytic capacitors. In case of higher AC voltage, they may burn with blast and catch fire.
